Abstract: weather fluctuations impact Sirex and Leptocybe pest, which results in wood loss in the forestry industry. Modelling the weather impact on these pests were performed using seven techniques. Most of the models overfitted the Sirex data. For Leptocybe the SVM performed the best with a TP rate of 22.31% and TN rate of 47.69%. Future research could investigate new features for example air quality and humidity.
